The utility model provides a kind of designing technique of flexible crystal silicon solar assembly;
Technical solutions of the utility model, it is characterized in that it is to make in the condition laminated of HTHP according to the order of the saturating cephacoria of height, EVA adhesive, crystal silicon solar energy battery layer, PCB module layer, EVA adhesive and solar energy back film successively, its key is connected to form by multiple PCB modules for PCB module layer, and the solar battery sheet of crystal silicon solar energy battery layer is positioned on each PCB module;
Described PCB module layer is made up of in the PCB of 0.5-2mm module thickness, the surrounding of PCB module is rhombus lug, between PCB module, connected by the summit of rhombus lug, rhombus lug summit place is through pre-cut processing simultaneously, in the time bearing certain dynamics, can make to disconnect between PCB module.
Between described crystal silicon solar cell sheet, connect or be connected in parallel by being coated with tin band, PCB module all has groove on the position of electrical connection painting tin band, prevents from being coated with tin band and PCB and rubs impaired.Described PCB module size is slightly larger than crystal silicon solar cell sheet size, crystal silicon solar cell sheet can be formed after battery strings according to setting gap electrical connection, is directly positioned in the PCB module of justifying, and technological operation is very convenient.
By saturating above-mentioned height cephacoria, EVA adhesive, crystal silicon solar energy battery layer, PCB module layer, flexible crystal silicon solar assembly after EVA adhesive and solar energy back film lamination is because the space of fillet is larger between PCB module, EVA adhesive cannot be filled whole spaces completely, can be recessed to form groove in PCB module junction, make after the connection disconnection between PCB in the doubling of exerting oneself, will be by high cephacoria thoroughly between every PCB module, EVA adhesive and solar energy back film flexibly connect, make whole flexible crystal silicon solar assembly there is good flexibility.
The saturating cephacoria of described height is ETFE film or PET film, has the advantages that light transmission is good, quality is light, wear-resisting, can effectively protect crystal silicon solar cell sheet; Described EVA adhesive is EVA material, has good light transmission and caking property, ensures the bonding reliability of levels, ensures the connection reliability between PCB module simultaneously; Described solar energy back film is: TPT material or TPE material, there is good barrier and weatherability, and can ensure that flexible solar components works long hours.Above-mentioned ETFE(ethylene-tetrafluoroethylene copolymer), TPT(polyvinyl fluoride composite membrane), PET(PETG), the copolymerization of EVA(ethylene-vinyl acetate), TPE(polyethylene film) be prior art, no longer statement herein.
Described flexible crystal silicon solar assembly, it is characterized in that it is that to select cell piece according to electrical property be full wafer or cutting blade, arrangement mode can be series connection, can be in parallel, also can connection in series-parallel and deposit, when its effect, can reach specific voltage, electric current and power requirement;
The preparation method of the utility model patent is as follows:
A: according to the size design justifying PCB module of having set;
B: crystal silicon solar cell sheet is electrically connected and forms battery strings according to the gap of setting;
C: whole string battery strings is positioned in PCB module;
D: battery strings, EVA adhesive, the solar energy back film of having good positioning by saturating height cephacoria, EVA adhesive, with PCB stack gradually and arrange from top to bottom, are finally pressed into flexible crystal silicon solar assembly under high temperature and high pressure environment.
Said method is in the time producing flexible crystal silicon solar assembly, without making each cell piece separately and PCB module positions, only battery strings and justifying PCB module need be positioned, compared with conventional solar components production technology, only increase one deck PCB, meanwhile, the quantity of PCB is more, and the flexibility of flexible solar components is better.
Flexible crystal silicon solar component design technical scheme of the present utility model adopts innovative technology, highly effective, technique is simple, can break through the complexity that the inflexible limitation of current crystal silicon solar assembly and flexible crystalline silicon component are produced, there is higher social benefit, economic benefit.
